Twitter agrees to buy artificial intelligence firm

Twitter has agreed to acquire a London-based artificial intelligence startup to make tweeted live videos look more professional. 

In a blog post, Twitter chief executive Jack Dorsey said he was buying Magic Pony Technology “so Twitter can continue to be the best place to see what’s happening and why it matters, first.”

Seeking to shore up slowing growth, the social media company has recently months begun emphasising video on its site.
